METAL WINDOW-SCREEN.

To all whom it may concern:

Be it known that I, Warrrnn CLAIRE SEN- NETT, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented a new and useful Metal Window-Screen, of which the following is a specification.

The present invention appertains to metal and improved device of that character.

The present invention contemplates the provisionof a unique metal. frame for window screens, the rails and stiles of the frame each comprising sections assembled in a peculiar manner, and adapted to receive or accommodate the edge portions of the meshed wire panel in a peculiar and effec tive manner.

It is also within the scope of the present invention to provide a metal window screen which will be of utmost simplicity in its construction, which will be neat and plain in appearance, which may be manufactured at a minimum cost, which will be convenient, practical, serviceable and efficient in its use, and the parts of which may be assembled and separated in a convenient and efficient manner.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that r changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a fragmental side elevation illustrating a corner portion of the improved metal window screen. Fig. 2 is an enlarged cross section taken through one of the frame members, and illustrating the parts or sec tions thereof assembled. Fig. 3 is a sectional view similar to Fig. 2, with the parts or sections separated, and illustrating them in position for assemblage.

The present metallic frame, embodies, as usual, the rails and stiles or frame members 1, which, however, in the present caseare of peculiar construction. Each of the rails and stiles or frame members embodies an inner channel 2 bent from sheet metal, and having Specification of Letters Patent. Patented Ngv, 10, 1914 Application filed May4,1914. scream. 836,286.

its flanges 3 and a of different Widths. The channel is relatively narrow, and the flanges 3 and a are relatively narrow and wide. The second section or elementof each frame member 1 is also in, the form-of a sheet metal channel 5, which is slightly Wider than the channel 2, and whichhas its flanges 6 and 7 of different widths. Thus,

the flange 6 is relatively narrow while the flange 7 is relatively wide. The back of the 1 mner channel 2 is disposedinwardly, while the back of the outer; channel 5 is disposed outwardly, the flanges 6 and 7 of the channel 5 being adapted to straddle; the flanges of the channel 2, with the relatively. narrow and wide flanges 6 and 7 of the channel. 5 overlapping the relatively Wide and narrow of the channel 2. The rela tively narrow and wide flanges of the outer and inner channels are thus reversed, which is of importance in assembling the channels as will hereinafter appear. The ends of the channels 2 of the frame members 1 are initered and soldered or otherwise. secured together as at 2e, while the ends of the channels 5 are mitered as at 5, but are detached, in order to enable the outer channels or sections to be readily applied to and removed from the respective channels 2.

In assembling the meshed wire or reticulated panel. 8 withthe frame, the panel 8 is placed against the relatively narrow flanges 3 of the channels 2, when the channels 5 are removed, and the edge portions of the panel 8 are tucked back in the channels 2, as indicated at 9 in Figs. 2 and 3. Then, to apply the panel-retaining channels 5 to the channels 2, the channels 5 are arranged angularly relative to the channels 2, as indicated in Fig. 3, and with the relatively wide flanges 7 standing across the edges of the flanges 3 and 4 of the inner channels 2.

Thus, the free edge of the flange 7 is adapted to readily move over the free edge of the flange 3, and the free edge of the flange 6 is adapted to readily move along the outer side or face of the flange l, when each of the channel members 5 is slipped home upon the respective channel 2. Thus, when the channels 5 are moved astride the channels 2, the panel 8 will be clamped between the 3 and 7 of the channels 2 and 5 respectively. Screws or other securing members 10 may then be engaged through the overlapping portions of the several flanges, to lock the channels 2 and 5 together, the screws 10,

however, being readily removable, in order to permit the channels to be withdrawn, from time to time, when the panel 8 is to be replaced.

It is of considerable moment that the channels 2 and 5 be constructed as above V pointed out, to enable the same to be readily assembled without the necessity of springing or bending the flanges of the channels when they are assembled. Furthermore, the edge portions of the panel 8, will bereadily accommodated between the two channels 2 and 5.

The present frame is comparatively thin, and its sides are plain'and unencumbered. The inner and outer edges of the frame are also closed andof smooth appearance. It is of course understood that the sheet metal channels 2 and 3 may be galvanized, oxidized, or otherwise finished or plated for purpose of wear and appearance.

Havin g thus described the invention, what is claimed as new 131- 1-. A window screen embodying a frame constituting inner channels having their ends mitered and secured together, and outer channels straddling the flanges of the aforesaid channels and having their ends mitered together, and a reticulated panel having its edge portions clamped between certain flanges of the inner and outer channels and tucked back into the inner channels.

2. A window screen frame comprising g frame members, each frame member constituting an inner channel having relatively narrow and wide flanges, and an outerchan- I nel having relatively narrow and wide 1 flanges, the ends of the inner channels being g secured together, the outer channels straddling the inner channels, and the relatively narrow and wide flanges of the outer channels 1 overlapping the relatively wide narrow i flanges, respectively, of the inner channels, and a reticulated panel clamped between the E narrow flanges of the inner channels and the wide flanges of the outer channels and hav- 1 ingits edge portions tucked 'back into the inner channels. 7 5

A window screen embodying a frame ii comprising frame members, each frame member constituting an inner channel having relatively narrow and wide flanges, and anouter chan'nelstraddling the inner channel and having relatively narrow and wide flanges overlapping the relatively (wide and narrow flanges, respectively, of the inner channel, the ends of theinner channels being secured together, a reticulated panel clamped between the relatively narrow and wide flanges, respectively, of the inner and outer flanges and having its edgeportions tucked back within the inner channels, and securing means engaged through the overlapped portions of the inner and oute'rchannels. ii i In testimony that I claim the foregoing as my own, I have hereto aflixed my signature inthe presenceof two witnesses.
